Abstract (en)
[origin: EP3599376A1] A wind turbine is provided. The wind turbine comprises: a generator (162), one or more power converters (20) arranged between the generator and a point of connection to a main transformer (5), and one or more wind turbine electrical components (8, 9, 10). The main transformer (5) is configured to connect a busbar (60) to an auxiliary wind turbine transformer, wherein the busbar is configured to receive electrical power from an electrical grid with a main voltage. The wind turbine electrical components are configured to be connected to the auxiliary wind turbine transformer (6), wherein a selection of the wind turbine electrical components is further configured to be connected to the busbar through a service voltage transformer (7) when the main transformer (5) is disconnected from the busbar. Systems comprising such wind turbines are also provided. Methods for connecting a wind turbine main transformer to a grid are also provided.
